BRUNO WIESSELMANN, OF HAMBURG, ASSIGNOR OF ON E-HALF TO VIILHELM LUCHT, OF ALTONA, GERMANY.

PENCIL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 423,845, dated March 18, 1890. Application filed December 27,1889. Serial Nc. 335,147- (No model.) Patented in Germany February 2l, 1889, No. 48,647.

.To @ZZ whom, t may concern: Be it known that I, BRUNO WEssELMANN, a citizen of the German Empire, residing at Hamburg, in the German Empire, have invented new and useful Improvements in Pencil-Sharpeners, (for which I have obtained a patent in Germany, No. 48,647, dated February 21, 1889,) of which the following is a specification. io This invention has for its object to provide a novel, efficient, and desirable pencil-sharpener, which canV be economically manufactured in large quantities by simple means; and to vsuch end theinvent-ion consists in the i 5 features of construction and the combination or arrangement of devices hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a plan view of a pencil-Sharpener. 2o Fig. 2 is a section along A B, Fig. 1. Fig. 2

is a detail view of a cutter. Fig. 3 is a seotion along C D, Fig. 1. Fig. -t is a plan view of a modification of Fig. 1. Fig. 5 is a section along E F, Fig. fl. Fig. G is a section along G I-I, Fig. 4. Fig. '7 is a plan view of a pencil-Sharpener with a cigar-tip cutter. Fig. 8 is a side elevation of Fig. 7. Fig. 9 is a plan view of a pencil-Sharpener with an eraserholder. Fig. 10 is a side elevation of Fig. 9. The sharpener is shown consisting of two plates or sections a h, each struck up with a semicircular projection to form a receivingspace h for the pencil, said plates being secured together in any suitableway, such as by bending of the edges.

In a suitable recess between the plates is arranged the knife or cutter m, the edge of which projects obliquely into the receivingspace h, whereby a pencil introduced into said space can be conically sharpened. The knife shown in Figs. 1 to 3 consists of a single suitably-bent steel plate, Fig. 2, and said knife is secured in place partly by iitting into the space between the plates and partly by having an opening o in one 'of its branches, into which opening ts a suitable shoulder or projection on one of the plates or sections.

In Figs. 4 to 6 the Sharpener is shown with an adjustable cutter, so as to enable the penn cil to be sharpened Vwit-l1 more or less taper. 5o The set-screw s, guided by the guide or nut 7c, enables the cutter to be adjusted to vary the taper produced by the cutter on the pencil. The cutter in this case consists of a massive piece of material and can turn either about 5 5 a lug or elevation on a plate or section-or about a bolt passed through the plates. The bolt is used if the knife is to be made removable, in which case the edges of the plates back of the knife are open or separate, so 6o that the knife can be removed or introduced through the opening. The spring t' continually presses the knife against the set-screw s.

The pencil-Sharpener, Figs. et to 6, is also combined with a device for cutting off cigaro5 tips. The cigar-tip cutter cis movably applied between the plates a l). Said plates are not united at this part along their edges and have play-room for the tip-cutter c and the spring f, lbent about the fo ur-cornered pivot or shank 7o t. The spring presses the tip-cutter c continually to its closed position. The shank t is held at its edges in four-cornered holes or depressions in the plates. If a cigar-tip is to be cut off, the tip-cutter by means of its proj ectin g handle is first opened. Then the tip of the cigar is inserted into the hole u, and the tip-cutter then being closed the cigar-tip will be cut off.

The pencil-sharpencr in Figs. 7 and 8 has 8o a lengthened form, and the plates a h are not united along the edges, but bymeans of the rivets e. The set-screws for the knife nz,in the case of Figs. 7 and S, also serves to hold the plates a, h together. pivot for the cigar-tip cutter c. The receiving-space 71 in said Figs. 7 and 8 is shown as being only formed in the under plate in the shape of a projecting cone.

In the construction shown in Figs. 9 and'lO 9o only one plate is employed-namely, the plate a, provided with the space 7L. On said plate the cigar-tip cutter c is secured by the' screw or pivot t. The knife m in this case sits about the set-screw s, said set-screw passing 95 through a slot, so that said screw, with the knife, can be adjusted relatively to the space 71,.

A rivet r serves as a A In addition to the cigar-tip cutter, the pencilsharpener has a holder q for a rubber or eraser, said holder q consisting of ahollow or recessed attachment into which the eraser of suitable form can be fitted and secured.

Vhat Iclaim as new, and desire t-o secure by Letters Patent, is#

I. A pencil-Sharpener consisting of a flat plate struck up with a semicircular projection to forni the pencil-receiving groove 7L, and a cutter m, formed separate from and attached to one side of the grooved plate in the plane parallel thereto and having an oblique cutting-edge extending diagonally into the pencil-recehing groove, substantially as described.

A pencil-Sharpener consisting of two iiat plates united together and each struck up with a seinicircular projection to forni between the plates a circular pencil-receiving space 71 and a flat cutter nl, arranged between and parallel to the two plates and having an oblique cutting-edge extending diagonally into the circular pencil-receiving space between the plates, substantially as described.

A pencil-Sharpener consisting of two fiat plates united together and each struck up with a seinicireular projection to form between the plates a circular pencil-receiving space 71, a cutter m, pivoted between the two plates and having its cutting-edge extending obliquely into the pencil-receiving space, a screw-nut, and a screw engaging the nut between the plates for adjusting the cutter more or less into the pencil-receiving space, substantially as described.

4. A pencil-Sharpener consisting of.' two plates united together and provided with a pencil-receiving space, a cutter movably arranged between the plates and having its cutting-edge extended obliquely across the pencil-receivin g space, and a screw for adj usting the cutter more or less into the said space, substantially as described.

5. A pencil-Sharpener consisting of a flat plate struck up with a semicircular projection to forni a pencil-receiving space, a flat cutter mounted on the plate with its cuttingedge extending obliquely into the pencil-receiving space, and a cigar-tip-cutter blade supported by the plate and niovingin a plane parallel to the latter, substantially as described.

G. A pencil-sharpcncr comprising a plate having a ci gar-tip-rcceiving orifice u, a pencilreceiving space h, and a cutter m, and having a swinging cigar-tip-cutter blade moving in a plane parallel with the plate to cut a cigar-tip inserted through the orifice therein, substantially' as described. I

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
